Mini wind turbines, solar panels and other small scale technologies could provide 30-40% of the UK's energy needs by 2050, according to the Energy Saving Trust (EST). Its report, Potential for Micro-generation, study and analysis, was commissioned by the Department of Trade and Industry (DTI). By 2050, micro-generation could help reduce CO2 emissions by 15% per year. Small wind has significant potential for near-term cost reductions and could contribute 6% of electricity demand and reduce CO2 by 4%. Capital grants could encourage uptake, but a fair price must be paid to domestic generators who export power into the grid, says the EST. The report will inform the DTI's micro-generation strategy due in the spring. "There is an increasing amount of interest and support for these technologies from politicians, industry and the public alike," comments Mari Martiskainen from the British Wind Energy Association. "It is vital that the government's micro-generation strategy ... takes bold action to make this potential into a reality."
